Description

[Detailed description of the invention] B Industrial application field The present invention relates to an incinerator for towers.

B. Conventional technology In Japan, when a funeral is generally held in the Buddhist style, there is a custom of offering a pagoda (sotoba), flowers (fresh flowers, artificial flowers), and food to the grave when the ashes are interred or memorial services are held.

The above-mentioned pagodas and offerings are to be disposed of after a certain period of time, and it is said that incineration is the preferred method of disposal.

Traditionally, pagodas and offerings have often been disposed of as ordinary garbage (household waste), and in rare cases, they have been incinerated in private incinerators; A garbage incinerator is used.

C. Problems to be solved by the invention However, in the case of conventional garbage incinerators, it is not possible to put a long toba (3 to 6 shaku in length) into the furnace as it is, so the toba is There is no choice but to cut it to length and put it into the furnace, but
Cutting up the pagoda in this way or incinerating it along with regular garbage in a garbage incinerator would lack solemnity due to the nature of the offering, and would therefore not be considered by most Japanese people. However, there are problems such as psychological resistance.

In addition, general garbage incinerators cannot be said to have very good incineration efficiency due to their structure, and the amount of smoke exhaust from the chimney inevitably increases, especially when burning raw garbage such as wet pagodas, fresh flowers, and food. As a result, temples and graves located in densely populated residential areas are at high risk of causing smoke pollution problems.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to efficiently incinerate a large number of toba from below in an upright state without cutting them, and also to make it possible to efficiently incinerate a large number of toba from below while incinerating them. The purpose of the present invention is to provide an incinerator for pagodas that can dry and burn fresh flowers, food, and other raw garbage by using the exhaust heat and flame of waste heat, and that can minimize the amount of smoke emitted during incineration. .

D. Means for solving the above-mentioned problems In order to achieve the above object, in the incinerator for towers of the present invention, a tower incinerator is installed in front of the furnace body, which is equipped with a chimney at the top and a garbage inlet on the side. The incinerator has a vertically elongated shape corresponding to the length of the toba, and is connected to the furnace body at the bottom so as to communicate with the incinerator, and the incinerator has a vertically long toba with an opening/closing door on the upper side. It has an insertion port and a combustion material input port with an opening/closing door with an air adjustment port on the lower side.

E. Effect: After inserting the required number of towers into the tower incinerator of the tower incinerator constructed as above in a vertically erect state through the insertion opening, the insertion opening is sealed with an opening/closing door. .

Newspapers and other combustible materials (kindled) are put into the lower part of the tower incineration furnace through the combustible material input port and ignited, and the firepower during combustion causes the lower part of the tower to catch fire.

After the material to be combusted is ignited, the input port is closed with an opening/closing door, and the adjustment port is adjusted so that an appropriate amount of air is sucked in depending on the combustion condition of the tower.

Since the above-mentioned tower insertion port is sealed by an opening/closing door, air cannot enter the upper part of the tower combustion furnace through the tower insertion port, so there is no possibility of flames moving upward, and therefore the tower is in the upright state. Since only the lower part of the pagoda will burn, the pagoda will descend from the bottom while burning sequentially, and will be able to maintain an almost upright position until it is completely burnt out.

Raw garbage such as fresh flowers, food, and other offerings are thrown into the furnace body through the garbage inlet.

Since the furnace body and the toba incineration furnace communicate with each other at the bottom, the flame and smoke during the toba combustion are introduced into the furnace body and pass through the food waste, and the waste heat is used to generate Moist combustible materials such as garbage will be dried.

The food waste inside the furnace body may be dried as described above and ignited spontaneously by the flame during the combustion of the toba, but a separate burner may be attached to the side of the furnace body to ignite the garbage etc. If you raise the internal temperature of the toba before burning it with a burner, you can improve the combustion efficiency of the toba, reduce the amount of smoke exhaust, and dry the garbage, etc. It is convenient because it can improve the combustion efficiency of raw garbage.

F. Example Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in Figures 1 to 4, fresh flowers, artificial flowers,
It is composed of a furnace body 1 that incinerates food, flower vases, and other raw garbage, and a toba incineration furnace 2 that incinerates only the toba.

The furnace body 1 is formed into a vertically elongated body with a rectangular cross section by an exterior material such as a steel plate with a refractory material attached to the inner surface.

The furnace body 1 has a chimney 4 extending upwardly at its upper part, and an inner cylinder 5 with both upper and lower ends open is vertically disposed at the center of the lower part of the furnace body 1.

A plurality of connecting plates 6 (four in the illustrated example) extend toward the center from the lower inner surface of the outer wall 3 of the furnace body 1, and the inner cylinder 5 connects to the furnace body 1 through the connecting plates 6. It is supported and held in the center of the inside.

From one side of the upper part of the inner cylinder 5, a cylindrical body 7 that penetrates the outer wall 3 of the furnace body 1 is arranged in a state of being inclined downward from its outer end to its inner end. A dust inlet 8 to the inner cylinder 5 is formed,
An opening/closing lid 9 is disposed at the outer end of the garbage inlet 8 so as to be openable/closed and sealed.

The inner cylinder 5 has a rotor 10 disposed at its lower end opening to support dust in a ventilated manner.

This roaster 10 is placed on a support 10b that is installed in a cross shape on an annular body 10a, and has a shape that allows ash to easily fall from the inner cylinder 5 to the lower chamber 11 of the furnace body 1, for example, a cross-sectional shape. It is formed into an equilateral triangular shape, a circular shape, or the like.

Further, a planar annular gap 12 is formed between the outer wall 3 of the furnace body 1 and the inner cylinder 5.

This space 12 is provided to guide flames and smoke generated during combustion of the tower, which will be described later, from the lower chamber 11 to the upper part of the furnace body 1, when the inside of the inner cylinder 5 is full of garbage. That is, it is provided to prevent smoke and the like from rising upward due to the pressure drop of the burnt material on the rostol 10.

Note that the inner cylinder 5 is preferably formed of a heat-resistant metal with good thermal conductivity, such as a stainless steel plate.

Further, it is preferable that the furnace body 1 has a burner attachment port 13 at a lower portion of one side thereof to attach a burner (not shown).

When the burner is installed in this way, the burner can be used to set the furnace internal temperature to an appropriate temperature (for example, 60°C).
C), it is possible to improve the combustion efficiency when actually burning the tower, and to extremely reduce the amount of exhaust smoke.

At the same time, when wet materials to be burned, such as food waste, are put into the inner cylinder 5, the materials to be burned can be dried in advance, so that food waste, etc. can be burned efficiently. This is convenient because it also reduces the amount of smoke emitted.

Incidentally, the tower incineration furnace 2 is connected to the front of the furnace body 1, and is formed into a vertically elongated shape using the same exterior material as the furnace body 1.

That is, the inner dimension of the toba incineration furnace 2 in the vertical direction, that is, the height H from the inner surface of the bottom wall 14 common to the furnace body 1 is set to be larger than the length h of the toba 15 by an appropriate dimension, The tower 15 is formed so that it can be inserted in a vertically elongated state without cutting, and the volume is formed so that a desired plurality of towers can be inserted.

Further, the above-mentioned tower incineration furnace 2 is provided with a tower insertion port 16 in the upper part and a combustion material input port 17 for kindling etc. in the lower part of the front face thereof.

The tower insertion opening 16 is formed with sufficient vertical and horizontal dimensions to allow the tower 15 to be inserted into the furnace 2 in a vertically long state.

Opening/closing doors 18 and 19 are provided at the tower insertion port 16 and the combustion material input port 17.
7 are pivoted so that they can be opened and closed by hinges 20 and 21 so that they can be hermetically sealed.

Toba insertion opening 1 by each opening/closing door 18, 19 mentioned above
6. As an example of sealing means for the incineration port 17, as illustrated in FIG. 22..., 23... are rotatably mounted on a support shaft 24. On the other hand, a wedge-shaped lever receiver 25 having an inclined surface 25a on the front side is fixed to the front of the opening/closing doors 18, 19. By rotating the levers 22, 23 in the direction of the arrow a shown in the figure with the doors 18, 19 closed, the levers 22, 23 slide on the inclined surface 25a of the lever receiver 25, and the lever receiver 25
Opening/closing door 1 by climbing on the front surface 25b of
8 and 19 are pressed into close contact with the opening edges of the insertion opening 16 and the input opening 17, thereby sealing the insertion opening 16 and the input opening 17.

The means for sealing the insertion port 16 and the input port 17 are not limited to the illustrated example, and other known means may of course be employed.

Further, an air adjustment port 26 is provided in the opening/closing door 19 of the input port 17.

The air adjustment port 26 is supported on a shaft 27a of a handle 27 so that an adjustment blade 26b can rotate freely within the opening 26a and adjust the opening amount of the adjustment port 26a by rotating the blade 26b.

Here, the reason why the toba inlet 16 is sealed with the opening/closing door 18 is that air enters the furnace 2 from the toba inlet 16, so that when the lower part of the toba 15 is burning, the flame moves upward. This prevented Toba 15
This is to allow only the lower part to burn when it is left standing.

Further, the tower incineration furnace 2 is communicated with the furnace body 1 via an incineration chamber 28 and a passage 29 provided at its lower part, and the lower chamber 11, and the combustion chamber 2
8, the lower part of the tower 15 is burned, and the flame and smoke generated are guided to the furnace body 1.

Furthermore, air adjustment ports 30, 31, and 32 may be provided at each side of the furnace body 1, lower chamber 11, and combustion chamber 28 as needed, as shown in the illustrated example.

In the above configuration, when using this to incinerate garbage such as the pagoda 15 and fresh flowers, the process is as follows.

First, put the required number of toba 15 into the toba incineration furnace 2.
... is inserted in an upright state, the opening/closing door 18 is closed and the tower insertion opening 16 is sealed.

Garbage such as fresh flowers and food is thrown into the inner cylinder 5 through the waste inlet 8, and the opening/closing lid 9 is closed.

Next, for example, old newspapers and other combustible materials to be kindled are inputted from the combustible material input port 17,
After igniting this, the door 19 is closed and the air adjustment port 26 is adjusted appropriately.

As the material to be burned burns, it spreads to the lower part of the tower 15, but the flames and smoke at this time do not move above the tower incinerator 2, but pass through the passage 29 from the lower chamber 11 of the furnace body 1 to the inner cylinder. 5 and through the gap 12 between the inner cylinder 5 and the furnace body 1. And at this time,
The garbage placed on the roaster 10 in the inner cylinder 5 is also dry-burned, and the smoke is discharged to the outside from the chimney 4.

In addition, if a burner is installed as in the illustrated example, the burner can be ignited in advance to heat the inside of the furnace to about 60°C, and then the toba 15 and garbage can be ignited. Furthermore, combustion efficiency can be improved and the amount of smoke exhaust can be extremely reduced.

Only the lower part of the tower 15 is burned in the combustion chamber 28, but the tower 15 descends as much as it burns, and is maintained in an almost upright position until it is completely burnt out.

G. Effects of the Invention Since the present invention is configured as described above, fresh flowers, food, and other raw garbage can be put into the furnace body 1, and the toba 15 can be cut into the dedicated toba incineration furnace 2. By inserting the toba in an upright position and burning only the lower part, it is possible to burn it to the end while it remains upright. Since the toba 1 does not stack up in layers etc.
5...The incineration efficiency of the tower 15... can be improved by the mutual circulation of air,
In addition, since there is no need for cutting, etc., not only is the effort saved, but also the solemnity is sufficiently satisfied.

In addition, the garbage, etc. in the furnace body 1 is dry-burned by the flame, smoke, and exhaust heat during combustion of the tower 15, so the combustion efficiency of the garbage, etc. is improved, and the amount of exhaust smoke is reduced. It can be used without any problems even in densely populated residential areas.
Furthermore, since the toba incineration furnace 2 is installed vertically and continuously in front of the furnace body 1, it has many advantages such as being able to be made smaller.
